Sorry, I don't get this.  The first paragraph above tells me that for a
given cluster event each <alert> is run once, with all recipients passed
as command line arguments to the alert executable.  But a single
invocation can only have a single set of environmental variables, so how
can you override instance attributes for individual recipients?
